The differences of cone crusher and jaw crusher

The specification of medium and fine cone crusher can be indicated by the movable cone bottom diameter. The working principles of medium and fine cone crusher are similar to the gyratory crusher. But they are different in structure compared to jaw crusher, the mainly differences are:

(1) The two cone shape of gyratory crusher are in steeply inclined, the movable cone is erect frustum cone ,and fixed cone is headstand frustum cone, which is mainly used to magnify the feeding end. The two cones of medium and fine cone crusher are both gentle dip erect frustum cones, and between the two cones, there is a certain length parallel crush section (parallel band), which is used to control the granularity of product, for the design of medium and fine crusher is based on the quality and capacity of crusher.

(2) The movable cone of gyratory crusher hangs on the beam in the upper of the machine, while the movable cone of medium and fine crusher supports at the lower spherical bearing.

(3) Gyratory crusher adopts dry dust keeper, while medium and fine crusher uses Water seal dustproof device.

(4) Gyratory crusher uses the rise and down of movable cone to adjust the discharging end, while medium and fine crusher adjusts the discharging width by adjusting the height of fixed cone (adjusting ring).

(5) According to the adjusting device and safety device of feeding end, the medium and fine crusher can be classified as spring cone crusher and hydraulic cone crusher. The working principles of spring cone crusher are consisted of movable cone and fixed cone with manganese steel liner plate. Movable cone mounts on the main shaft 15 by press, one side of main shaft inserts into the bell mouth of excentric sleeve, when the excentric sleeve moves, it can drive the movable cone to cycle.

In order to guarantee the cycle movement of movable cone, its bottom surface are sphere and be supported on the spherical bearing. The weight of movable cone and main shaft is bearing by spherical bearing and rack.
